| 摘 要： | 在江西省上栗县通过无重复对比试验,研究了配方施肥在大田试验条件下对早稻生物产量以及肥料利用率的影响,结果表明:与常规施肥相比,配方施肥促进了早稻籽粒和秸秆对N、P、K养分的吸收,提高了养分的当季利用率,从而有利于增加早稻籽粒和秸秆生物产量。各养分对早稻地上部生物产量的增产效果依次表现为N>K>P。

| Abstract: | A field experiment was carried out to study the effects of fertilizer recommendation on the biomass of early rice and fertilizer use efficiency in Shangli county of Pinxiang,Jiangxi province.The results showed that: as compared with fertilization in a conventional way,fertilizer recommendation promoted the N,P,K nutrient absorption in grain and straw of early rice,and increased the fertilizer use efficiency.Based on this,the biomass of grain and straw was finally increased.The increasing effect on above-ground biomass of early rice was N>K>P. |
